I have created a centralized cert store on a file store and need to put in a .pfx file. I created a website on IIS 8 on server 2012 and created a CSR which was then given to godaddy which generated the wildcard cert. The certificate request was then completed in IIS and I can see the cert in Personal Store however I am not able to export to a pfx file to store in the centralized cert store. We are planning to use the same certificate for multiple web servers. Has anyone dealt with this before?
